BATH OR OTHER TUB.

SPECIFICATION forming part of Letters Patent No. 541,371, dated June 18,1895.

I Application filed April 1, 1892. $erial No. 427,357- (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. MARSTON, of Dover, in the county ofStrafford and State of New Hampshire, have invented a new and usefulImprovement in Bath or other Tubs, of which the following is a full,clear, and exact description.

My invention relates to an improvement in tubs either for bath or otherpurposes, and also to an improvement in like receptacles, as ordinarytubs; and has for its object to provide a means whereby water whenplaced within the tub or receptacle may be maintained at a uniformtemperature for whatever length of time it may be desired, and also toprovide a means whereby the temperature of the water contained in thetub may be raised or lowered conveniently and expeditiously, and wherebyalso when the temperature has attained a predetermined degree, either ofheat orcold, the supply of hot or cold water will be automaticallycutofi when necessary.

It is another object of .the invention, in bath and in other tubs, toprovide a shower or spraying device capable of supplying, when desired,sprays from the sides or in direction of the center of the tubs, andfurther, to utilize the tub to heat the air surrounding the bather andto. maintain the required tempera ture in the room in which the tub isplaced, the tub acting as a radiator, and also to pro vide a means forsupplying fresh air in the immediate vicinity of the tub and of removingfoul air therefrom.

It is a further object of the invention to construct a tube or likereceptacle possessing all the features above set forth, and which willnot only be simple and durable in construction, but also exceedinglyeconomic and of great utility. V

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views. 1

Figure 1 is a longitudinal vertical section through a bath-tub,illustrating the application of the invention thereto, the section being taken practically on the line 1 1 of Fig. 2. Fig. 2 is a plan viewof the tub; and Fig.

3 is a vertical transverse section taken eshot water, and in making theconnection between the inner'and outer jackets of the tub,

the inner jacket, which is really the tub proper or the receivingsection of the tub, is provided with a flange, and through the medium ofthis flange the connection between the two jackets is eifected. Thus theupper marginal face of the tub, as shown in Fig. 2, may be practicallyflat or otherwise.

A vent or air cook 12, is usually placed at any convenient point andconnected with the chamber B of the tub; and a faucet 13, is also placedin direct connection with the inner chamber B, and this faucet isadapted, when desired, for supplying Water to the bathing or washingchamber of the tub which is formed by the inner jacket 10; but if inpractice it is found desirable, an independent hot or cold water faucet14,0rafaucet supplying both hot and cold water may be used in connectionwith the tub, the latter faucet receivingits supply from a sourceforeign-to the in-.

terior chamber 10 of the tub. It will be unthe boiler, pipes 20, 24 andchamber B will be under pressure from the water main or other V sourceand hence will flow through the fancet 13.

In order that the te erature of the interior chamber B may beascertained, a thermometer 15, is so placed that its bulb enters thesaid chamber, and the scale may be read by any one adjacent to or withinthe tub. Fresh air is ordinarily introduced adjacent to the bathing orwashing compartment of the tub by means of a tube 16, in communicationwith the outside of the compartment, which tube extends verticallythrough the-two jackets of the tub, and terminates at the top of theouter jacket preferably, the top being provided with a cover 17, capableof being removed to permit a flow of fresh air into the room in whichthe tub is located, or the cover may be compartments.

closed over the pipe or tube to cut-0E such supply.

The air-supply pipe or tube is usually located at one end of the tub, asshown in Fig. 2; and at the opposite side of the same end an ofl'takepipe 18, is placed, which extends downward from the tub and takesthe'air from beneath the bottom of the tub and conveys it from the roomin which the tub is-located.

Preferably the inner compartment B of the tub is sub-divided into twocompartments by means of apartition 19.

tub, as it is necessary that communication should be established betweenthe two sub- This partitionwill cause the heating medium to How from oneend of the chamber to the other and then return, since both pipes 20 and24 are at the sameend. Therefore the partition is usually stopped at oneend of the inner jacket.

Above the partition 19 a pipe 20, is-made'to enter the compartment B inthe tub, and-this pipe is adapted to supply hot water to-thatcompartment, thehot water supply being controlled by a valve 2l,-andusually above the valve a cold water pipe-22,'is connected with the hotwater supply pipe,the cold-water pipe being also provided with a valve23. Thus hot or cold water, or both commingled, may besupp'lied to thecompartmentB of-the tub as desired.

The water from the compartment B, is returued to its source of supplythrouglrthe medium of a return pipe 24, which enters the compartment 13at or near its bottom.

At opposite sides of thetub, in the bath' ing or washing compartmenteither at-the top or bottom, a sprinkling or shower tube 25 is located.When the tubes are located near the tops of the tubs they throw thewater in the direction of its center, as shown in Fig. 3. Thesesprinking tubes are preferably connected and are valve-controlled,andthey also preferably receive their supply of water from the compartmentB of the tub. Thetub is also provided, when itis designed for use as abath tub, with covers 26, capable of being shut down so as to cover themajor portion of the bath and permit the occupant to obtain all thebenefit possible from the steam or hot vapor arising from the water intaking a bath.

It is very desirable that the water in the bath should be maintained atan even temperature; and in the event that the bath should become toowarm, the temperature becoming too high, the supply of hot water may beautomatically cut off. This is "preferably eifected throughthe mediumof-a thermostat, of any approved construction'located within the bathingorwashing'compartment of the bath'in a manner to be operated upon bytheheat.

The thermostat shown in the drawings comprises a bulb or box 27, a tube28 leading Thispartition, how-. ever, does not extend from end to endof'the therefrom and-a casing 29 connected with the opposite end of thetube and provided with the usual flexible diaphragm having a short rod29 extending through the upper end of the said casing and contactingwith the lower side of the weighted end of the lever 30. The short armof the lever 30 is connected with the arm 32 of the hot water valve by acord 31 passing over a suitable guide pulley and provided at its lowerend with a weight.

The lever 30 is provided with a weight 33 and normally extends in ahorizontal position, but when the temperature of the contents of the tubrises above a predetermined degree the air or other fluid in the bulb orbox 27 will be expanded and force the column of'fluid in the tube 28against the lower side of the diaphragm, thereby causing the latter tomove the'rod 29 upward against lever 30. As the weighted end of-lever30rises the weighted 1 cord 31 descends and moves the arm- 32 tocolorations, by letting it remain a comparatively longtime in the tubwith a gentle heat applied insteadof by boiling.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A combined bath tub and radiator,-comprising thebath tub'proper, a jacket inclosing the same and forming the closedchamber B, hot water circulating pipes communicating with the saidchamber, and afaucet communicating with the said chamber and-with thetub proper, substantially asset forth.

2. The combination with the jacketedtub, the internal chamber of whichis divided horizontally and longitudinally into two compartments, whichcommunicate at one end, of the hot water. flow and return pipescommunicating respectively with the non-communicating ends of saidcompartments, substantially as set forth.
